General Rhizobia references

Here is a html version endnote bibliography database that I used for my PhD thesis in about 2006 . It is incomplete and will remain so. I wont be updating this again but hopefully will be of some use to someone. I did not use all of these in my thesis !
There is PDF version, too. Also a nicer version can be found on my CiteULike page.

There are 824 papers, sorted by author.
